If such an amplifier is used in OFDMA based systems, it will cause serious degradation. This degradation will be both in terms of the reduction in BER and the generation of out of band noise. In this paper we have worked on the linearization method of the amplifier. This work is on a hybrid methodology, in which estimation of the model is performed in frequency domain and compensation is performed in time domain. The downlink preamble of the IEEE802.16e system is used here for the estimation purpose. The results for the suppression of spectra are shown at the end.English802.16em 802.16mHigh power amplifierNon-linearityOFDMAWuMAXCellular telephone systemsCommunication systemsFrequency division multiple accessGlobal system for mobile communicationsMobile computingPhotodegradationPower amplifiersFrequency estimationConference Paper10.1109/VETECS.2009.5073716
